An n-type helical molecule perylene diimide (PDI2) has been explored as an efficient interfacial layer between TiO<sub>2</sub> and perovskite, which can restrain the light-soaking instability and reduce hysteresis in perovskite solar cells. A champion device PCE of 19.84% has been achieved after incorporating the PDI2 interlayer.
